Fulton County Police were dispatched to Kelly's home on Stoneleigh Drive shortly after 4:30 p.m. Upon arrival officials discovered Kelly was unconscious and non-responsive. Emergency technicians administered CPR on the scene before Kelly was transported.

According to the Fulton County Medical Examiner's office, Kelly was pronounced dead at Atlanta Medical Center -- South Fulton around 7:30 p.m. Wednesday.

The cause of death appears to be a drug overdose, according to Fulton County Police. The Fulton County ME's office will not confirm the actual cause of death until a toxicology report is performed.

Kelly and his bandmate Chris "Daddy Mack" Smith" were discovered by music producer and Atlanta native Jermaine Dupri at a local mall in 1992. During performances, Kris Kross wore their clothes backwards -- it later became their signature look.

The group is most famous for their single, Jump. In 1992, Jump ranked No. 3 on the Billboard Top 100 list. Most recently, Kelly performed at the So So Def 20th Anniversary Concert in February.

Kelly's mother, Donna Kelly Pratte, along with The So So Def Family released a statement early Thursday morning, saying:

"It is with deep sadness that we announce that our beloved Chris Kelly has passed away on May 1. To millions of fans worldwide, he was the trendsetting, backwards pants-wearing one-half of Kris Kross who loved making music. But to us, he was just Chris - the kind, generous and fun-loving life of the party. Though he was only with us a short time, we feel blessed to have been able to share some incredible moments with him. His legacy will live on through his music, and we will forever love him."
